Be itknown'that I, HUGO C. SoHLoE, a

Brookings, in the county of Brookings and State of South Dakota, have invented certain new and useful-Improvements in Car- Heater Registers, of vwhich the following is' ication. his invention relates broadly to a car heater of the type used in connection'with automobiles, but it has more particular reference to an improved register or heat controlling device for an appropriately designed heater.

he primary object of the invention is to provide a register of the above kind, depend- -ing for its operation upon its association and relationship with a motor vehicle engine exhaust muiiier.

Another object of the invention is to provide a register of the above character that embraces the desired qualities of simplicity and durability of construction, as well as efficiency in operation.

Still another object of the invention is to provide a device -which may be readily installed upon existing motor vehicles with comparative ease and at a nominal cost, the device embodying a. register for readily regulating the amount of heated air delivered into the vehicle.

Other objects will appear as the natureiof IL'S . the invention is better understood, and the same consists in the -novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a view partly in section, and partly in elevation of an exhaust manifold heater equipped with an improved register, constructed in accordance with the present invention.

Figure 2 is an enlarged transverse sectional view. taken substantially upon the line 2-2 of vFigure 1, and

Figure 3 is an enlarged top lan view of a portion of the device shown in Figure 1, to reveal details of the register. l

Referring more in detail to the drawing, 5 indicates the portion of an exhaust pipe of a motor vehicle engine that leads to a conventional form of muier 6, and 5a indicates the portion of said exhaust pipe which leads from said muilier 6 and has its rear end open to .the atmosphere, inthe well known usual manner.

In carrying out the present invention, a suitable drum 7 is disposed about the casing of theI muilier 6 in concentric spaced relation to the latter, and the ends of this drum are placed in closed relation to the muilier casing by means of inturned annular flanges 8 provided u n the ends of the drum 7 as shown in Figure 1, the drum 7 being rigidly secured in place by any lsuitable manner such yas by soldering the flanges 8 to the muler casing. An annular cylindrical chamber 9 is provided, in this manner, between the muffler casingv and the drum 7, about which air may circulate so as to be heated by contact with the casing of the muffler 6, that becomes heated due to the qhot exhaust gases passing therethrough. The bottom of the vdrum 7 is provided with a port 10, through which f air may pass to enter the chamber 9, and associated with this port is a damper 11, by means of which the amount of air admitted .to the chamber 9 may be regulated, which damper is preferably of the slide type as shown. Disposed at the rear of the port 10 is a forwardly and downwardl projecting defiector plate 12 of scoop li e form by means of which the air is eiectively directed into the chamber 9 u on forward travelling movement of the vehicle. The parts so far described form no part ofthe patentable novelty of the present device.

As observed from the foregoing and more particularly from the annexed claim, the novelty of the present device residesmore particularly in the construction of the so called register. In the present instance, this register embodies a heat conveying pipe or conduit 13 which is connected at its lower end to one end of the aforesaid casing 7 and extends upwardly therefrom. The upper end of the outlet pipe 13 projects into an opening provided in the floor 14 of the car to be heated, the up er end of said pipe 13 being substantially ush with the upper surface of the ioor 14 as shown clearly in Figure 1. A damper is provided upon the upper end of the outlet pipe 13, land this damper preferably consists of a rotatable cap 15, having a plurality of spaced openings 16 lin the top thereof, whichopenings are adapted to be brought into or out of registration with similar openings 17 provided in asuitable wall formed on the uplper end of the outlet pipe 13 as shown. T e outlet pipe 13 is also provided with aside port 18,

and the cap 15 is similarly provided with a side port 19, said ports 18 and 19 bein so related as to register;y with* each other w en the ca 15 is turned to dispose the openings 16 an 17 out of register. It follows that the openings 18 and 19 are also so related that when they are out of register, the side port 18 wilI be closed while at the same time, the orts or openings 16 and 17 are regis tered). Thus, means is provided for simultaneously allowing all of the heated air'to pass through the up r end of the outlet pipe 13 into the car w ile preventing any of the same from being diverted to the atmosphere through the side port 18, such means also constituting meanswhich may be operated for diverting all of the heated air. through the side port 18 and preventing any of the same from passing through the upper end of the outlet pipe 13 into the car. Likewise, a portion of the heated air may be diverted through the port 18 t0 the atmosrhere, while the remaining por- 1,54a,soo

-o ned while t tion thereof `is allowedto pass into the car, because the oplenings 17 may be partially eport 18 itgpartially opened w en the cli-11p 15 1s adjus to a particular position. ence, the temperature of the air within the car may be regulated to a. nicety.

What I claim as new 1s:

In a device of the class described, a hot air conveiing conduit formed at its up r end with ot air escape ports and formedpien one side of its wall at a pointl` below the upper endlwith an additional rt, a closing cap telescopically and rotatalglgf fitted upon the upper end of the conduit, and provided .at one end with ports adapted to register with the first named ports and provided in its side wall with asupplemental port adapted to register with the aforesaid additional port, the last named port in the cap being disposed with re tto the ports at the end of the ca s0 t at when the latter are fully registere with their co-acting rts in the conduit, the port in the side wal of the latter will be closed.

In testimony whereof I a'ix niy signature.
